DRIER.

Specification of Letters Patent.

Patented March 3, 19081.

Application filed May 29, 1907. Serial No. 5576,2467.

T all whom it may concern:

Be it known that I, HENRY W. RAYNER, a citizen of the United States, and a resident of Eagle Lake, in the county of Colorado and State of Texas, have invented certain new and useful Improvements in Driers, of which the following is a specification.

My invention is an improvement in driers, and is especially designed for drying bagasse, or crushed cane, milled or diffused sugar cane from a sugar mill; and the invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawings Figure 1 is a perspective view, parts being broken away and others shown in section of a drier embodying my in vention. Fig. 2 is a side elevation of the drier. Fig. 3 is an end elevation of the drier. Fig. 4 is a detail viewillustrating the bearings and frictionclutch mechanism of the sprocket wheels.

Heretoiore specially constructed furnaces have been employed for burning the bagassc on account of the large percentage of moisture which the solid or crushed cane and diffused sugar contains.

By,.my invention 1 seek to provide specielly constructed driers and on account of the expense of heat for evaporating the moisture in the begasse l utilize the waste heat of any character or any character of heat resulting from products of combustion used under a steam boiler, and the specified waste heat to be considered waste heat it used ini tially for steam raising purpose under a boiler and then sent into the open air either through brcechings or stack. The waste heat as here indicated is the flue gases or the resultant'ol heat after it has been utilized as heat ol direct combustion to raise siczim un der a. boiler, in heating the drier for driving oil the moisture.

in the construction shown, I employ casing A having side doors B and end doors and provided with a hopper l) through which the bagasse may be supplied to the carrying mechanism by which it is shifted from the hollow heating boxes presently describml. i.

also provide the casing A with an oft-told A communimitmg through a pipe A with any suitable l'or'u of suction [an it, by which the air within the :asing may he turned oilin the operation of the invention as presently d cscribcd. 'lhe suction tan E may deliver to and also spaced. apart from the through the pipe 9 any suitable st ack if convenient, or may deliver to the air as preferred.

Within the casing A I provide a series of hollow boxes of which I have shown three, F, F and W, the several boxes overlying each other as shown in Fi 1, and being arranged to extend longitudinally in the direction of length of the casing A and being spaced apart bod of the casing A so that air may circulate around the several heating boxes F, ii and i in the practice of the invention. to one end of the upper box h by a lluefond circulates thence to the opposite end of the box i whence it is conducted by e lluef to the adjacent end of the next lower box F, circulates thence to the opposite end of the box F which is connected by the thief with the adjacent end of the next lower box F and circulates thence in said box to the. opposite end thereof, where it discharges through the flue gto a suction tan G which delivers the heated air, gases, etc. so received back into the casing A within which it circulates around the heating boxes h, F, and F and is delivered through the oft-take A by the operation of the suction fan E in the use of the invention as pres ently described.

As shown the boxes F, l? and F overlie and the delivery ends of the boxes F and if" terminate short of the receiving ends of the next lower boxes F" and i respectively, so that the material delivered oil the end of the box i will be received on the be); l and dischargml tlmncc to the box i in too use of the apparhtus. 'lhe doors ii and U permit co11- venicnt access to the interior of the casing for cleaning or repairing the interior ports of the apparatus, as will be readily understood from Fig. l.

Heat is supplied through the iluefprel ci ably by connecting said lluef with a smoke stack so the drier may be heated by the utilization of the exhaust, wnstc and surplus heat from such stack, the lluc gas l'rcrpicntly reaching a very high temperature, and thus facilitating the dricrs operation by rapidly driving oll' moisture, as oil! be understood from the drawings tlhain carriers are cl'nployed for moving the bagassc over the n gger surfaces of the be: i i and ,Qin lhe construction shown the upper run of th chain carrier H o ierstes over the box l*, and the lower run of lleat is delivered fifi lii is returned by perates overthe box F, the carrier moving close to the and the chains at peratingin angle Fig. 1. The carrier for the lower box has its chains h and slats h operating over the box F? with the chains h of the upper and carrier operatmg in angle iron tracks 2' At one end the operate over idle pulleys H as shown in Fig. '1. carriers H and h and H while at their otl carriers are suitably driven.

lower runs of said and 'L, ch ain ier ends, the said The chain carrier H has its sprocket pulleys H connected 15 with the drive pulley H? which may be suitably driven from any source of power and the said sprockets H journaled in boxes J are mounted on a shaft whlch. may be ad usted by screws J, as will be understood from .the

drawings. The journals Wheels, it will be, noticed side of the casing A so they of all the sprocket are arranged outmay be lubricated and the lubrication will not be seriously af fected by the heat within The sprockets H the casing. of the upper carrier connect by friction clutches K with the drive sprocket H and the sprockets H of the lower carrier are sprockets PF in 30 nected by a sprocket H which may suitable manner.

In the operation mounted similarly to the adjustable boxes and confriction clutch K with their drive be driven in any of the described construction, it will be noticed the bagasse supplied 35 through the hopper upper heat b'ox' F e upper run of the carrie charged at the delivery D is received upon the and moved therealong by r H until it is dis end of the-box F onto the ireceiving end of the box F along which 40 'it is moved by and delivered I box F along which ii'ery end of said box charged through a suitabl desired receptacle.

The heat maintained it is ca the lower run of the carrier H onto the receiving end of the rriod to the deliv F whence it may be dise outlet into any being supplied through the flue f is circulated through the boxes F, F and F and the out of the box F through the fan fluesfandf and I the flue g whence G and delivered. mto the casing through which it circulates around the bagasse in such manner as to operate thereon not only by the heat contained inthe gases, etc. so circulated through the casing A, but also by reason of the draft aiding in the evaporation process, as will be understood by those skilled in the art.

claim:

1 A drier substantially as herein described, comprising a casing, a series of heating boxes arranged therein one above the other, with the delivery end of each box terminating short of thereceiving end of the next lower box, connecting ilucs between the delivery ends ofeach box and the receiving ends of the next lower box, a the upper box,- an outlet flue leading from the lower box, a suction fan connecting with said outlet flue and having a discharge flue leadin to the casing, a suction fan connected with the oi fta'ke of the casing, chain carriers movable over their respective heating boxes, and angle iron tracks for the chains of the said carriers, substantially as set forth.

2. In a drier substantially as described, the combination of a casing, a series of drying boxes therein and arranged one above the other, with the delivery end of each box discharging to the receiving end of the next lower box, flues connecting the said boxes, a supply flue leading to the upper box, a discharge flue leading from the lower box, a fan supply flue leading to in connection with said discharge flue, and .a I

return flue from said fan to the casing, whereby heat may be circulated through the boxes and may thence be withdrawn and circulated through the casing surrounding the boxes, substantially as set forth.

3. The combination with a casing, and heating boxes therein, forming bases over which the material to be dried may means for supplying a heating medium to the heating boxes, and means for withdrawing the said medium from the boxes and circulatin'g it through the case surrounding the boxes, substantially as set forth.
